Many teens, especially on Long Island, have unrealistic budgets in mind when shopping for prom.

David's Bridal and Men's Wearhouse are working together on a national Facebook dance contest called "Dance Dance Prom" to help.

To enter, interested participants should learn the official dance at http://apps.facebook.com/dancedanceprom/ and then record and submit their own version by April 5. Dancers can go solo or collaborate with up to 10 friends.

The video with the most votes by April 26 will win the $20,000 grand prize-- $10,000 for the teen and $10,000 for his or her school.

Two other winners will receive a $100 gift certificate to David's Bridal or Men's Wearhouse for up to 10 people in their video.
